LDCRE Lock-up Solenoid for Subaru Lineartronic CVT TR580/TR690 — Black 3.2–3.7Ω Direct-Fit Replacement

LDCRE lock-up solenoid for Subaru Lineartronic CVT (3.2–3.7 ohm) is a direct-fit transmission solenoid designed to control the torque-converter lock-up and AWD transfer clutch in select TR580/TR690-equipped Subaru models.

This high-quality replacement matches common OEM reference numbers (31825AA050 / 31825AA051 / 31825AA052 and related part codes) and is intended for vehicles equipped with Subaru Lineartronic CVT TR580 or TR690 transmissions. It is sold individually and comes in the black lock-up solenoid style; buyers should verify the part number and vehicle compatibility before ordering. The unit provides the electrical resistance range specified and installs into the transmission valve body or transfer housing where it controls hydraulic flow for lock-up and AWD engagement.

How does this solenoid fit my specific Subaru model?

The LDCRE solenoid is manufactured to match the mounting and electrical characteristics used on many Subaru CVT models that utilize TR580 or TR690 transmissions. It replaces several factory numbers and fits numerous Legacy, Outback, Forester, Impreza, Crosstrek and other Lineartronic-equipped models from roughly 2010–2017. Always compare the part number on your existing solenoid to ensure a correct match.

• Direct replacements for 31825AA050 / 31825AA051 / 31825AA052 and similar codes.
• Compatible with TR580/TR690 CVT transmissions used across Subaru model years cited.
• Designed for the black lock-up solenoid style commonly found in OEM valve bodies.
• Sold as a single AWD/lock-up solenoid; valve body gasket or O-rings not included.

What performance and electrical specs should I expect?

This solenoid is specified at roughly 3.2–3.7 ohms resistance, matching the electrical range required for many Subaru lock-up and transfer clutch controls. Proper resistance ensures predictable actuation timing and hydraulic pressure modulation inside the CVT valve body. If your vehicle’s diagnostic trouble codes or bench testing point to a failed solenoid, replacing it with the correct-ohm unit restores expected electrical behavior.

• Resistance: approximately 3.2–3.7 ohms per manufacturer specification.
• Electrical connector and pin arrangement designed to match OEM wiring harnesses.
• Engineered for valve-body installation where it regulates lock-up or AWD clutch pressure.

Which symptoms indicate this part may need replacing?

A failing lock-up or transfer solenoid can cause drivability issues related to torque transfer, AWD engagement, or CVT shift feel. Common signs include transmission-related fault codes, inconsistent AWD lock-up behavior, or unusual shift patterns. Diagnostics such as resistance checks and trouble codes (e.g., transfer or pressure control faults) help confirm whether the solenoid is the likely cause.

• Transmission warning light or stored CVT/transfer clutch codes in the ECU.
• Irregular torque-converter lock-up or inconsistent AWD engagement.
• Bench-tested coil resistance out of the 3.2–3.7Ω range indicates replacement need.

Who this is for: Technicians, DIY mechanics, and Subaru owners who need a direct-fit replacement for a failing lock-up or AWD transfer clutch solenoid in Lineartronic CVT TR580/TR690 transmissions. This part is intended for those who can verify the existing part number and are comfortable with transmission valve-body or solenoid-pack replacement procedures. If you require multiple solenoids, valve-body seals, or professional installation, factor those items into the repair plan.

Package includes:

• 1 x LDCRE AWD lock-up solenoid (as pictured)
• Replacement numbers covered listed in product details; please confirm fitment prior to purchase.
